and/or downloading, copying, modifying, displaying, distributing or use of any
software and/or data from FreeSurfer (collectively, the "Software") constitutes

PART A. CONTRIBUTION AGREEMENT

License to MGH with Right to Sublicense ("Contribution Agreement")

As used in this Contribution Agreement, "you" means the individual contributing
the Contribution to FreeSurfer and the institution or entity which employs or
is otherwise affiliated with such individual in connection with such Contribution.

This Contribution Agreement applies to all Contributions made to FreeSurfer,
including without limitation Contributions made prior to the date of first publication
of this Agreement. If at any time you make a Contribution to FreeSurfer, you
represent that (i) you are legally authorized and entitled to make such Contribution
and to grant all licenses granted in this Contribution Agreement with respect
to such Contribution; (ii) if your Contribution includes any patient data, all
such data is de-identified in accordance with U.S. confidentiality and security
laws and requirements, including but not limited to the Health Insurance Portability
and Accountability Act (HIPAA) and its regulations, and your disclosure of such
data for the purposes contemplated by this Agreement is properly authorized
and in compliance with all applicable laws and regulations; and (iii) you have
preserved in the Contribution all applicable attributions, copyright notices
and licenses for any third party software or data included in the Contribution.

Except for the licenses granted in this Agreement, you reserve all right, title
and interest in your Contribution.

You hereby grant to MGH, with the right to sublicense, a perpetual, worldwide,
non-exclusive, no charge, royalty-free, irrevocable license to use, reproduce,
make derivative works of, display and distribute the Contribution. If your Contribution
is protected by patent, you hereby grant to MGH, with the right to sublicense,
a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable
license under your interest in patent rights covering the Contribution, to make,
have made, use, sell and otherwise transfer your Contribution, alone or in combination
with any other code.

You acknowledge and agree that MGH may incorporate your Contribution into FreeSurfer
and may make FreeSurfer available to members of the public on an open source
basis under terms substantially in accordance with the Software License set
forth in Part B of this Agreement. You further acknowledge and agree that MGH
shall have no liability arising in connection with claims resulting from your
breach of any of the terms of this Agreement.

YOU WARRANT THAT TO THE BEST OF YOUR KNOWLEDGE YOUR CONTRIBUTION DOES NOT CONTAIN
ANY CODE THAT REQURES OR PRESCRIBES AN "OPEN SOURCE LICENSE" FOR DERIVATIVE
WORKS (by way of non-limiting example, the GNU General Public License or other
so-called "reciprocal" license that requires any derived work to be licensed
under the GNU General Public License or other "open source license").
